Water that remains, or stagnates, and collects, or that remains long, and becomes altered, or that becomes yellow and altered, in the bottom of a valley: pl. [of pauc.] أَحْيَالٌ and [of mult.] حُيُولٌ. (K.) -A2- Also a subst. from الاِحْتِيَالُ; (S, K;) and so ↓ حِيلَةٌ, with kesr; (S;) or ↓ حَيْلَةٌ [perhaps a mistake for حِيلَةٌ]; (K;) and ↓ مَحَالَةٌ, and ↓ مَحَالٌ. (AZ, S.) [See حِيلَةٌ in art. حول.) ― -b2- Strength, power, might, or force; syn. قُوَّةٌ; as also حَوْلٌ; (TA;) of which it is a dial. var. (S, Msb.) So in the saying, لَا حَيْلَ وَلَا قُوَّةَ إِلَّا بِٱللّٰهِ. (S, * Msb, TA. [See حَوْلٌ.]) So, too, in the phrase, in a form of prayer, اَللّٰهُمَّ ذَا الحَيْلِ الشَّدِيدِ [O God, Possessor of great might]: perverted by the relaters of traditions into ذا الحَبْلِ, with ب. (TA.) If it be a contraction of حَيّلٌ, originally حَيْوِلٌ, its proper place is art. حول: otherwise, this is its proper place. (TA.)
